General
Waterbomb is a skip in the Category Extension Smack% found by everyday_aussie on the 8th of November 2021. It is done by triggering a checkpoint up in the tunnel leading to another tunnel which leads to the first sluice gate, and then dropping bomb onto the water to jump over to the other side. This can be done with as many bombs as you want, but the less you drop the more time you save. The skip saves about 8 seconds if done optimally, but is not implemented in Smack% due to its incredible difficulty.
